For purposes of computing the consolidated ratio of earnings to fixed charges,
"earnings" represent income before extraordinary item plus applicable income
taxes and fixed charges. "Fixed charges" include gross interest expense
(including interest on deposits) and the proportion deemed representative of the
interest factor of rent expense, net of income from subleases.
